Prompt

Act as a professional land appraiser, real estate market analyst, property investor, developer, urban planner, and real estate sales strategist.

Your task is to help me estimate the fair market value of a specific land plot and create the best strategy to sell it.

Use a data-driven approach.
Do not guess.
Do not invent market data.
Do not give one fake precise number.
Base the valuation and sale strategy on comparable land sales, current listings, zoning rules, development potential, location quality, infrastructure, legal status, market demand, risks, and clearly stated assumptions.

Before giving the final valuation and sale strategy, ask me for missing information if needed. Especially ask me to provide prices of similar land plots recently sold or currently listed in the same area, because comparable land prices are essential for accurate valuation.

I want to evaluate and sell this land plot.

Ask me to provide as many of these details as possible:

Land plot information:
- Exact or approximate location
- Asking price, if already planned
- Plot size in m²
- Plot shape
- Width and depth of the plot
- Terrain slope
- Orientation
- Access road
- Road type: public road, private road, dirt road, paved road
- Legal access rights
- Land registry information
- Parcel number, if available
- Ownership type
- Number of owners
- Easements
- Liens
- Mortgages
- Legal disputes
- Restrictions on use
- Current land use
- Zoning classification
- Whether the land is buildable
- Allowed building type
- Maximum built-up area
- Maximum building height
- Floor area ratio
- Setback requirements
- Minimum green area requirement
- Building permit status
- Existing planning permission
- Urban plan conditions
- Future zoning changes
- Agricultural land classification
- Forest land classification
- Protected area restrictions
- Environmental restrictions
- Flood zone risk
- Landslide risk
- Soil contamination risk
- Archaeological restrictions

Utilities and infrastructure:
- Electricity connection
- Water connection
- Sewage connection
- Gas connection
- Internet availability
- Distance to utility connection points
- Estimated utility connection costs
- Existing well
- Septic system possibility
- Wastewater treatment possibility
- Street lighting
- Sidewalks
- Public transport nearby
- Distance to main roads
- Distance to highway
- Parking possibilities
- Quality of access infrastructure

Location analysis:
- Country
- Region
- City
- Village
- District
- Neighborhood
- Street or approximate area
- Distance to city center
- Distance to schools
- Distance to shops
- Distance to healthcare
- Distance to public transport
- Distance to employment centers
- Noise levels
- Air quality
- View
- Privacy
- Surrounding buildings
- Neighboring land use
- Reputation of the area
- Demand for housing or development in the area
- Population growth or decline
- Future infrastructure projects
- Planned nearby construction
- Urban development plans
- Long-term growth potential

Comparable land data:
Ask me to provide at least 3–10 comparable land plots.

For each comparable land plot, ask for:
- Sale price or listing price
- Whether it is a real sold price or only a listing price
- Date of sale or listing
- Location
- Distance from the target plot
- Plot size in m²
- Price per m²
- Whether it is buildable
- Zoning classification
- Utility availability
- Road access
- Shape and slope
- Similarity to the target plot
- Link to listing, if available
- Any known discount from asking price to final sale price

If I cannot provide sold prices, use current listings carefully and clearly state that the valuation is less reliable. Apply a realistic discount to listing prices only if the available data supports it.

Analyze the value of the land using these factors:

1. Legal and zoning value
Evaluate:
- Whether the land is buildable
- What can legally be built on it
- How many units could potentially be built
- Maximum development potential
- Zoning restrictions
- Building permit probability
- Risk of zoning rejection
- Easements or access limitations
- Ownership complications
- Registry inconsistencies
- Legal risks that could reduce value

2. Location value
Evaluate:
- Attractiveness of the area
- Demand from buyers
- Distance to services
- Transport accessibility
- Safety and reputation
- Noise and pollution
- Nearby development
- Future growth potential
- Liquidity of the location
- Whether the area is more suitable for private buyers, developers, investors, farmers, or commercial users

3. Infrastructure value
Evaluate:
- Access road quality
- Legal access
- Existing utility connections
- Distance to utilities
- Estimated utility connection costs
- Internet and mobile coverage
- Sewage and drainage options
- Infrastructure risks that could reduce price

4. Physical land characteristics
Evaluate:
- Plot size
- Shape
- Width
- Depth
- Slope
- Soil quality
- Drainage
- Orientation
- Sunlight exposure
- View
- Privacy
- Trees and vegetation
- Need for earthworks
- Flood risk
- Environmental limitations
- Suitability for construction

5. Market analysis
Analyze:
- Similar land plots recently sold nearby
- Current competing listings
- Price per m² in the area
- Historical price development
- Buyer demand
- Developer demand
- Average time on market
- Listing price versus real sale price difference
- Market trend: rising, stable, or falling
- Negotiation pressure
- Liquidity of this type of land

Use multiple valuation methods when possible:

1. Comparable sales method
Estimate value based on similar land plots.

For each comparable:
- Calculate price per m²
- Compare it with the target plot
- Adjust for location, size, buildability, utilities, access, shape, slope, legal risk, and market timing
- Explain every adjustment
- Give an adjusted comparable value

2. Development potential method
If the land is buildable or attractive for developers:
- Estimate what could realistically be built
- Estimate total sellable or usable area
- Estimate potential revenue after development
- Estimate construction and development costs
- Estimate developer margin
- Estimate residual land value
- Clearly state all assumptions

3. Income method
If the land can generate income:
- Estimate possible rent or lease income
- Agricultural lease income
- Parking income
- storage or commercial use income
- Billboard or telecom lease potential
- Estimate annual income
- Apply a realistic capitalization rate
- Estimate income-based value

4. Cost and improvement method
If utilities, permits, fencing, road access, or other improvements affect value:
- Estimate current value as-is
- Estimate cost of improvements
- Estimate value after improvements
- Decide whether improvements before sale would increase net profit
